Note: *Heat Exhaustion: Usually occurs in healthy individuals who have exercise induced hypovolemia. Example: Joggers. Clinical Signs: Normal temperature, wet pale skin, tachycardia, syncope, vomiting/diarrhea. Treatment: Heat exhausted patients are always fluid depleted. IV fluid therapy can help to correct fluid and electrolyte imbalances. **Heat Stroke: The patients most susceptible are the inactive, the elderly or the overactive healthy youth. Phenothiazines, tricyclics, antihistamines, amphetamines, alcohol, and diuretics may potentiate heat stroke. Clinical Signs: High body temperature with ALOC, dry hot skin, seizures, tachycardia. Treatment: Heat stroke patients require immediate rapid cooling. The most effective method is evaporative cooling achieved by wetting the skin and moving air across the body.
